摘　　要：目前铜渣资源化利用主要采用选矿法,处理后仍有大量尾渣无法有效利用。故将铜渣视为含有铜铁金属、高氧化硅无机材料且含高热值的资源,对铜渣进行资源化处理。熔融条件下对铜渣进行还原处理回收含铜铸铁,尾渣用于制备矿棉,实现了熔融铜渣的高附加值利用。该技术处理铜渣产品附加值高、能耗低,且具备一定的市场空间,具有较好的发展前景,可进行推广应用。Currently,beneficiating method is the main treatment method for resource utilization of copper slag. But there is still a mountain of tail slag having no valuable use after treatments. In the research,the copper slag was taken as a resource containing copper and iron metal,silicon oxide inorganic materials and rich in high calorific value,and the resource utilization treatment was carried out. Under molten condition,the copper cast iron was extracted from copper slag,tailing slag was used for making mineral wool,and high added value utilization of molten copper slag became true. This treatment technique of copper slag has high added value,low energy consumption,and has a certain market prospect. The development prospect of the technique of copper slag is good,which should be extended for application.
